On a coordinate plane, trapezoid K L M N is shown. Point K is at (negative 2, negative 4), point L is at (negative 4, negative 2), point M is at (negative 2, negative 1), and point N is at (negative 1, negative 2).
In the diagram, KL = 2 StartRoot 2 EndRoot, LM = StartRoot 5 EndRoot, and MN = StartRoot 2 EndRoot. What is the perimeter of isosceles trapezoid KLMN?

StartRoot 2 EndRoot units
StartRoot 5 EndRoot units
3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot u

step-by-step explanation:

the word superfluous means unnecessary

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

x< -17/2 hope this

the answer is  

c.

90.0π cm^2

hope you got it.
